Wind Issues

Wind Issues

High winds led to the edge metal detaching from the wood blocking on this PVC roof. This is why you stagger your fasteners, folks. Pay a little extra for quality assurance next time you have a roof put on.

A common result of wind scour is the loss of aggregate surfacing on built-up roofs. More a maintenance issue than an urgent repair item, it should be addressed by coating the area or re-installing the aggregate in order to prevent the deterioration of the exposed asphalt due to long-term UV exposure.

4. Codes: See "SECTION 1609 WIND LOADS" in the 2015 International Building Code for wind zone-related design considerations. Available on the UpCodes website. See below for information on residential buildings.

7. Technical: "Wind Effects on Asphalt Shingles" is a thorough, well-sourced, and well-illustrated technical paper made available by Haag Engineering. Gives you a good understanding of the subject, and helps with identifying wind-related roof damage.
